Updating firmware on magic jack
If you're using a Windows PC, the easiest way to manually install updates on a Nexus device is to use a program called Nexus Root Toolkit.The utility was developed by Wugfresh to provide a nice, mouse-friendly interface for this whole process, and I've covered it with an in-depth guide in the past.
Even when a connection between an internet phone service and a fax machine works, often it is not reliable. Even when a test fax works, the reliability of the connection is not guaranteed.While the guide outlines updating to Lollipop, the steps will be exactly the same if you're updating to Marshmallow.If you don't own a Windows PC, or if you'd simply prefer not to use the Nexus Root Toolkit, manually updating your Nexus device is still fairly simple.Google has finally released the next version of the world's leading operating system—Android 6.0 Marshmallow.This latest iteration isn't as much of a visual overhaul as Lollipop was, but it packs in more new functionality than almost any update before it.Awesome features like Now on Tap, granular permissions control, and a deep sleep battery-saving feature called Doze round out the highlights, but there is far more to it than that. Owners of most devices will have to wait on their manufacturers to tweak Marshmallow to their liking before an update will come through, but even Nexus owners will have to wait on Google's staged rollout, which can take as long as a month.
Luckily though, Android 6.0 is already available for download, so if you're up to the task, you can manually install Marshmallow on your Nexus device right now.
There are no direct fax features built into Magic Jack.
According to Magic Jack, connecting a fax machine should work.
